I'm afraid we need clarification first...what do you mean by "reconfigure an interface with an IPv6 address"? Do you mean adding a new IPv6 address to an interface? If so, I'm not sure why you referred to the following part of RFC2461 (btw the RFC was updated by RFC4861): > [1] RFC 2461 section 7.2.6 paragraph 1: > > In some cases a node may be able to determine that its link-layer > address has changed (e.g., hot-swap of an interface card) and may > wish to inform its neighbors of the new link-layer address quickly. this example talks about the case where the link-layer address changes for an existing address, not where a new address is configured. Could you elaborate? --- JINMEI, Tatuya Internet Systems Consortium, Inc. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
